To analyze the given data from the table:
-
Mali:
- Literacy rate: 26%
- Percent living on less than $1/day: 51%
-
Zimbabwe:
- Literacy rate: 91%
- Percent living on less than $1/day: 56%
-
Ghana:
- Literacy rate: 65%
- Percent living on less than $1/day: 30%
-
Democratic Republic of the Congo:
- Literacy rate: 67%
- Percent living on less than $1/day: 59%
Now let's evaluate the options based on the data:
-
A. Higher literacy rates result in higher income levels.
This is not supported by the data. For example, Zimbabwe has a high literacy rate (91%) but a high percentage of people living on less than $1/day (56%). -
B. Higher income levels result in higher literacy rates.
This option also does not hold true universally. Mali has the lowest literacy rate (26%) and a significant proportion of people living in poverty, while Ghana has a higher literacy rate (65%) and a lower poverty percentage (30%). However, Zimbabwe has a high literacy rate but still a considerable poverty level. -
C. Higher literacy rates result in lower income levels.
This is not accurate based on the evidence provided. -
D. Higher literacy rates do not necessarily result in higher income levels.
This statement accurately reflects the data. We see that while Zimbabwe has a very high literacy rate, a significant percentage of its population still lives in poverty, indicating that high literacy does not guarantee high income or low poverty levels.
Given the analysis, the best answer is:
D. Higher literacy rates do not necessarily result in higher income levels.
